Application filed August 1%,1916. Serial Elle. li ifiS t.

of Washington, have invented certain new aml-usefnl Improvements in lloa't'Operated Indicators; and I do lowing to be a hereby declare thefolfnll, clear, and exact descrip tion of the invention, such as willenable others skilled in the art to which it appcr-' tains to make anduse the same. This invention relates to float operated in dicators ofthe type particularly designed for use in connection with explosiveengines for indicating the quantity of oil contained in the crank case.

The invention has for its object to provide an improved indicatorincluding a float housiu which is suspended tromthe upper Dart oi thecrank case of the engine and is entirely independent of the bottom partso as to permit the latter to be readily removed when necessary.

Another object is togenerally improve and simplify indicators forexplosive engines and render them practical and eiiicient and alsoreadily adaptable explosive engines.

With these and other objects to numerous types oi in View, the

invention consists in the novel construction,

combination and arrangementof parts as will be hereinafter specificallydescribed;

claimed and illustrated in the accompany ing drawing, in which: I

Figure 1 represents a side elevation of an explosive engine, partly insection, illustrating the improved indicator applied thereto,

Fig. 2 represents an enlargediragmentary sectional view through thecrank case oi" the engine, illustrating a portion of the indicator indetail g Fig. 3 represents an elevation of the indicating part of theindicator,

Fig. t represents a front elevation, similar to Fig. 3, illustrating amodified type of the indicator, and

Fig. 5 represents a longitudinal sectional view through the upperterminal of the bendable guide for the flexible operating element.

Referring to the drawing in detail, wherein'similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates generally a well known type of explosive engine includingthe usual upper and lower crank case sections 6 and 7, respectively, thelower section 7 being detachably secured to the upper section 6 in orderthat access may be had to the connecting rod and crank shaft hearings.

in the accompanying drawing the invention is shown as applied to a motorvehicle, the dash board 8 of which is represented in The improvedindicator comprises a float housing 9', having oil ports 10 adjacent thelower end and an inwardly directed flange 11 fori'ned at the lower edgethereof to prevent the float 12, which is arrangedwithin the housingfrom dropping therefrom when the bottom section 7 of the crank case isremoved. The flange 11 of the housing simply rests upon the bottomsection of the crank case and is entirely independent thereof so topermit the bottom section to be detached independently of the floathousing.

A cover 13 is removably fitted over the upper open end of the housing 9and is formed with an integral, flange 14;, which is rigidly andpermanently secured to the lower terminal of a tubular guide 15. Theguide 15 preferably formed of bendable metal and. is extended upwardlythrough an aperture the top part 6 of the crank case.

it ring 16 is fastened to the top section 6- and is formed with anintegral flange 1'? receiving the tubular guide 15. A set screw 18 isfitted in an internally screw threaded aperture formed in-the flange 17and engages the tubular guide 15 whereby the housing 9 is suspended fromthe top crank case seclion. and is held in position afterthe removal ofthe bottom crank case 7.

The tubular guide 15. is extended to the dash board or other convenientpoint upon the motor z 'chicle or other object and is connected with atube 19 having a slot 20 there in. A sight glass tube 21 is confined inthe tube 19 between the terminal of the guide 15 and a plug 22 fitted inthe upper end of the tubefli).

A stem 23 is connected with the float it), extends upwardly within thelower terminal of the guide 15 and is rigidly secured at its uppeterminal with the the flexible actuating member 24. The oppositsterminal 0? the flexible member Q4 is adjacent end oi too extended intothe transparent tube 21 and is the slot 20 in the; tube l9,

and may housed or referred to in connection with markings on a plate 26fastened in venting displacemen front of the tube 19 to indicahe of oilcontained in the lower crank case. .i

in the modification of the invention illustmted in Fig. 4 the end of theflexible men with arod 27, having at the quantity section 2 of the eer24 is connected line marked thereon adapted to he read in connectionwith the markings on the plate 26 to accurately indicate the quantity ofoil in the crankcase of the engine. fWhat I claim is:'' 1. Incombination, ed for use .in connection with an engine crank ease of thesectional oil-containing type comprising an upper and a lower section,en actuating float for the indicator and adapted for location in thecrank case, a housing for said float havir g an apertured lowerterminal, an inwardly directed flange at the lower terminal of thehousing, preof the float and conan oil indicator adaptet woe baseanhzptuxi "to mow bottom of the lower section 11k case, and means foradjustubly i l gthe housing from the upper section of thecmni; caseindependently of the lower section thereof.

2. in eomhin' on, an engine provided with a crank case, said crank caseincluding an upper section and :1 lower section detachahiy securedthereto, and an oil. indicator suspended from the top crank case sectionand being independent of the lower detache-hie section, whereby thelatter may be removed independently of the indicator to ma pose theinternal mechanism thereof.

In testimony whereof I affix my signature in presence of a witness.

GEORGE G. BELDEN.
